Starting with its just released third issue, the Code4Lib Journal is using the Creative Commons Attribution License for its articles, making this freely available journal an open access journal under the strictest definition of that term (sometimes called "full open access").
Here's an excerpt from the editorial that discusses this change:
In order to facilitate the ability of our readers to build upon the ideas presented in the Journal, beginning with Issue 3 all articles are licensed under the Creative Commons Attribution (CC-BY) license. The CC-BY license lets you reuse, share, and build upon the work presented in the article, as long as you credit the author for the original creation. This licensing is required for inclusion in the Directory of Open Access Journals (DOAJ) and to receive a SPARC Europe Seal. Code snippets included in the text are included under the CC-BY license. For other code included with an article, we recommend, but don’t require, an open source license. We are contacting all authors with articles published in previous issues to request they license their previously published Code4Lib Journal articles under the CC-BY license.
